SBIR Phase I: Engineered Lumber from Sawmill Residue

这个小企业创新研究（SBIR）第一阶段项目将探索利用锯木厂生产的低价值残边来制造一种结构质量的工程木材复合材料，称为结构股材（SSL）。当圆木被锯成长方形的木材时，会产生边缘。SSL的概念是将这些边缘切割成线，定向排列，然后粘合并压缩成高价值的产品。边缘材料目前用于造纸用的低价值木屑。SSL制造过程应该产生高附加值的木材产品，大大减少浪费，减少对自然资源的需求，并提高锯木厂的效率。第一阶段的研究将为实现最佳SSL工艺提供基本的理解，并证明其在锯木厂操作中的可行性。第二阶段将演示SSL原型制造设施的操作。SSL制造有望大幅提高锯木厂的运营效率，同时减少锯木厂运营对环境的影响。通过拟议的工艺，最多可将14%以上的森林原料转化为高价值的木材产品。

9860586 This Small Business Innovation Research (SBIR) Phase I project will explore use of low value residual edgings from sawmill operations to manufacture a structural quality engineered wood composite called Structural Strand Lumber (SSL). Edgings are created when round logs are sawn into rectangular pieces of lumber. The SSL concept is to cut these edgings into strands, align them directionally, and then glue and compress them into a high value product. Edging material currently is used for low value wood chips for paper making. The SSL manufacturing process should yield a high value added wood product, dramatically reduce waste, reduce demand on natural resources, and increase sawmill efficiency. Phase I research will provide a fundamental understanding for enabling optimal SSL processes and demonstrate their feasibility in sawmill operations. Phase II would demonstrate the operation of a SSL prototype manufacturing facility. SSL manufacturing is expected to increase the efficiency of sawmill operations dramatically, while reducing environmental consequences of sawmill operations. Up to 14% more of forest raw materials could be converted to high value wood products with the proposed process.
